Warning ! "Module level import is not at the top of the cell"

 

The "Module level import not at top of cell" warning often occurs when you have Python module imports within a cell in a Jupyter notebook, but those imports are not at the top of the cell.

In a standard Python script, it is good practice to place all imports at the beginning of the file for better code organization and clarity. However, in a Jupyter notebook, cells are independent units of code, and cell order is often significant to the flow of execution.

The warning is issued because some linting tools may be configured to follow stricter standards, as if they were parsing a regular Python script. To handle this in Jupyter notebooks, some specific linter settings can be adjusted to recognize the unique structure of notebooks.

Certainly! To address this issue, you can consider configuring the `pyright` linter, which is often used by VSCode for Python linting. You can create a `settings.json` file in your VSCode workspace or user settings and add the following:

json : 

{

    "python.linting.pyrightArgs": ["--disable=W0611"],

    "python.linting.pylintArgs": ["--disable=W0611"]

}

This configuration disables the `W0611` warning, which is the warning for "Module level import not at top of cell," in both `pyright` and `pylint`. It should help silence these warnings specifically inside Jupyter notebooks in VSCode.

Note: Ensure that you have the appropriate linter extensions installed in VSCode for these settings to take effect.

Harmonizing Database Operations in a .NET 5 Services Architecture

When facing the challenge of integrating the Unit of Work in a .NET 5 services architecture, applying the dependency injection pattern emerges as a clever solution. For instance, configuring each service with its own instance of the Unit of Work maintains cohesion and avoids circular dependencies. This approach provides an elegant way to handle separate database contexts, allowing independent operations in each service.




Example:

csharp

public class ServiceA

{

    private readonly IMyUnitOfWork _unitOfWork;

    public ServiceA(IMyUnitOfWork unitOfWork)

    {

        _unitOfWork = unitOfWork;

    }

    public void ExecuteOperation()

    {

        // Service A logic

        _unitOfWork.ExecuteSQL("INSERT INTO TableA VALUES (@param)", param);

    }

}

public class ServiceB

{

    private readonly IMyUnitOfWork _unitOfWork;

    public ServiceB(IMyUnitOfWork unitOfWork)

    {

        _unitOfWork = unitOfWork;

    }

    public void ExecuteOperation()

    {

        // Service B logic

        _unitOfWork.ExecuteSQL("INSERT INTO TableB VALUES (@param)", param);

        // Save changes only in the context of Service B

        _unitOfWork.SaveChanges();

    }

}

By adopting this approach, you harmonize database operations in a services architecture, enabling a smooth execution of independent business logics without compromising the consistency of the database context.
